TONE GLARIFIER Application led April 1,

This invention relates to tone claritiers for use with musical instruments, such for example as a radio receiving set, a phonograph, a band or orchestral instrument.

.a The device may be disposed outside of a musical instrument or in the sound emitting throat thereof, and the distance of the device of, my invention from the instrument may be varied inorder to vary the loudness of the IH sound, the sound being louder the nearer the device is to the instrument.

An object of the invention :is the provision of a tone clarilier of novel and efficient structure.

l# Other objects will be appreciated by those skilled in the art upon reading the following specification.

The invention will be fully and comprehen- Sively understood from a consideration of the 1" following detailed description when read in connection with the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described, and, therefore, such changes and modifications may be made therefrom as do not ali'ect the spirit of the invention nor ex# ceed the scope thereof as expressed in the appended claims.

In the drawings:

Fig. l is an elevational view of a phonograph partly broken awa Fig. 2 is a plan view o the interior structure of one form of my invention, the casing therefor being partly in section and the cover for the casing being broken away.

w Fig. 3 is a vertical section taken on line 3-3 of Fig. 2.

Fig. 4 is an elevational view of a radio receiving set or phonograph and an elevational View of the device of my invention set before the musical instrument.

Fig. 5 is a view similar to Fig. 2, showing another form of my invention.

Fig. 6 is a vertical section taken on line 6 6 of Fig. 5.

Fig. 7 is a perspective view of still an- 1931. Serial No. 528,959.

other form of m invention, the cover for the casing being brolien away to show the interior structure.

Fig. 8 is a view similar to Figs. 2 and 5 and shows the form of invention depicted in Fig. 55 7;y and Fig. 9'is a vertical section taken on line 9 9 of Fig. 8.

Referring to the drawings for a more detailed description thereof, and at first to Figs. 60 2 andBin which one form ofmy invention is shown, the numeral 1() indicates a casing comprising a bodyl portion 11 of generally rectangular form. The casing also comprises Y a bottom 12 secured to the body portion 11 65 bv means of screws 13. A cover 14 is provided for the casing and secured to the body portion 11 by means of screws 15. The front part of the casing is provided with a screen 17 having a plurality of apertures 18 therein to allow sound from a musical instrument to enter the casing. The screen 17 is secured to the casing by being disposed in Vertical slots 19 formed in the sides of the casing. The screen may additionally be soldered to the casing which is preferably of metal, although it may be of any other material. The rear wall 11a of the body portion 11 of the casing is provid-ed with apertures 21 to allow sound to be emitted from the casing. The so number and size of the apertures 21 may be varied in accordance with the requirements,

`which vary with the type of instrument with which the device of my invention is used. The louder the sound emitted by a musical instrument the more will be the number of apertures 21 provided. A series of spaced parallel bailles 23 are secured to the bottom 12 of the casing 11 by means of brackets 25 which are secured to the baffles by means of rivets 2G, and to the bottom 12 of the casing by means of rivets 2G. The batlies 23 are vertical and are disposed on their edges as shown.' The bailies 23 as shown in Figs. 2 and 3 eX- 95 tend at right angles to the front and the back of the easing and parallel with the sides thereof. .another series of parallel spaced plates, set on their edges, is provided, these plates being designated by the numeral 27 and be- 100 A pass between tbe b ing secured to the bottoni l2 ol the casing by means of brackets 29.

Brackets 29 are secured to the battles 27 by means of rivets 30 and are secured to the bottom l2 of the casingby means ol rivets 3l. The bales 27 are disposed at an angle to the battles 23, respectively, each pair oit baes comprising; a baille 23 and a battle 2T forming;

a V. The front ends ol3 the battles 23 and their corresponding battles 2i' are slightly spaced apart as shown at 33 in Fig. rl`he battles A27 are preferably somewhat thicker than the baliles 23 as shown in Fig. 2. .ein end baille 23 is preferably bent outwardly as shown at 23a in Fig. 2. Back ont the baes 23 and 27 is disposed a vertical toraininated plate 35 having apertures 369 the nuinber ol" which apertures may be varied in accordance with the peculiarities ot tbe instrument Witb. Whicb the tone clarifier is used, tbe louder the tones from the musical instrument tbe more apertures 3G there will be. 'llbis plate 35 assists thebatlles 23 andv27 in producing tone clarification.

The louder tbe sound trono a. musical instrument the greater will be tbe which the 23 will be disposed relative to the ballles 2l' and the ivill be longer the louder tbe sound. troni the musical in-l struinent.

Reterringnoiv to ldigs. slowing inodilication ot iny :invention9 tbe s Aructure ot tbe casing' is similar to described shown in Figs. 2 and ldloivever instead o'l" providing tbe casingI with apertures 2l as in Figs. and 3, a screen.
